A prince had some monkeys trained to dance. Being naturallygreat mimics1 of men's actions, they showed themselves most aptpupils, and when arrayed in their rich clothes and masks, theydanced as well as any of the courtiers. The spectacle was oftenrepeated with great applause, till on one occasion a courtier,bent on mischief2, took from his pocket a handful of nuts andthrew them upon the stage. The monkeys at the sight of the nutsforgot their dancing and became  monkeysinstead of actors. Pulling off their masks and tearing theirrobes, they fought with one another for the nuts. The dancingspectacle thus came to an end amidst the laughter and ridicule3 ofthe audience.
